Headless JS 后台任務未在 React-Native 中運行

Question

import {AppRegistry} from 'react-native';
import App from './App';
import task from './src/task';
import {name as appName} from './app.json';


//AppRegistry.registerComponent('App',()=>App);
AppRegistry.registerHeadlessTask('SomeTaskName', () =>
task
);

package com.convertwebsitetoapp;
import android.content.Intent;
import android.os.Bundle;
import com.facebook.react.HeadlessJsTaskService;
import com.facebook.react.bridge.Arguments;
import com.facebook.react.jstasks.HeadlessJsTaskConfig;
import javax.annotation.Nullable;

public class MyTaskService extends HeadlessJsTaskService {

  @Override
  protected @Nullable HeadlessJsTaskConfig getTaskConfig(Intent intent) {
    Bundle extras = intent.getExtras();
    if (extras != null) {
      return new HeadlessJsTaskConfig(
          "SomeTaskName",
          Arguments.fromBundle(extras),
          5000, // timeout for the task
          false // optional: defines whether or not  the task is allowed in foreground. Default is false
        );
    }
    return null;
  }
}

task.js
module.exports = async (taskData) => {
    console.log('Demo')
    
  };

我是 React-Native 的新手。 嘗試在 react-native 中使用無頭 js 創建應用程序當我在oncreate方法中啟動 MyTask 服務時，應用程序崩潰並且無法打開。 當我在沒有組件registerheadlessjs任務的情況下注冊時，我收到錯誤為“未調用registercompoent ”如果有人有，請給我一個簡單的例子。

提前致謝

return new HeadlessJsTaskConfig(
      "SomeTaskName",
      Arguments.fromBundle(extras),
      5000, // timeout for the task
      true// optional: defines whether or not  the task is allowed in foreground. Default is false
    );

將假改為真
